The roll39 tically disposed side walls l5, iii, a bottom I! and is mounted on ashaft 40 which extends through a normally closed drain IS. The trough l2has bearings M at the rear ends of a pair of adjustable a series ofspaced supporting legs is depending spring controlled positioningdevices 2 for the from bottom ll. The trough I2 is of the depth, wiperroll 39. The devices iii are slidably length and width desired and maybe empolyed mounted at their front ends in the heads 24' of 5 thesupports it. Each of said devices d2 includes a combined stop andadjusting nut :13 at its front end. The shaft do is mounted in thecutouts 22. The shaft t projects from side wall it of the trough and hasfixed thereto gear wheel 35. The devices :32 resiliently maintain thewiper roll at a point substantially centrally of front of and againstthe periphery of a glue applying roll 56 which is of materially greaterdiameter than roll 33. The said devices 62 act as a safety means in casea foreign solid material is in the glue and comes up between the rolls53. The roll 16 is carried by a shaft which is journaled in. the cutouts23 and projects from the sidewall id of the trough. The shaft ll hasfixed thereto a gear 68 and a pinion G5. The latter meshes with anddrives gear Anchored, to the side wml it? of the trough is a bearing 59in which is jomnalled a stub shaft 56 carrying a pinion and a pulley 53.The pinion meshes with and drives the gear 48. The pulley is operatedfrom the driv ing connection 5: which leads from motor The section iinot only includes the supports 2%, 3E but also a pair of superposedguide rolls 56 55, a combined material holding and guide roll above andrearwardly of roll 55, a series of spaced parallel pick-up or pick-offfingers 5?, a pair. of connecting rods 58, 59, a holding bar (ill forthe fingers 51, a carrier 66 for the fingers 522a platform or table 62for the material which is to be operated upon, a pair of springcontrolled latching members 63 for the supports 2%, 3d, pivots E i forthe members 655, aligning inclined cutouts 64', aligning verticalcutouts 65, aligning vertical cutouts 66, and a pair of adjustableclosures 6?, each common to a cutout 65 and 66.

The supports 29, 3D consist of forward parts 68, intermediate parts 69of greater height than parts 68 and rear parts ill of greater heightthan parts 69. The cutouts 6d, 65 open at the top edges of the parts 69.The cutouts 66 open at the top edges of parts F0. The closures 67 aremounted on the top edges of parts 69 and are adjustably connected to thelatter by the retaining screws ll having large heads. The rolls 5d, 55and 56 are carried by the shafts l2, l3, and M respectively. When themachine is in active position, the roll 50 is arranged over roll 39 and.positioned in prom imity but spaced from the front of roll 15; the roll55 is arranged over and extends rearwardly from the roll 54; the roll 55is disposed in spaced relation to the upper portion of the front of roll46; the roll 56 is arranged above and rearwardly of roll 55 and inspaced relation to the latter; and the roll 56 is positioned over andslightly forward of the vertical median of roll 46, as well as beingspaced from the latter. The shafts l2, 13 extend into the inclinedcutouts 64. The shaft it is seated in the cutouts 65. The pick-upfingers 5'! are arranged over roll 55 rearwardly of and in proximity tothe guide roll 56.

The pick-up fingers are of like form and each consists of a plate 15gradually increasing in width from rear to front. The forward end 16 ofplate 15 inclines rearwardly from its lower to its upper end. The bottomedge ll of plate '15 inclines downwardly from rear to front. The plate15, in proximity to its rear end, is formed with an opening 78 andbetween its vertical median and forward end is provided with an opening19 arranged below opening I8. The side marginal portions of the plate 15bordering the end 16 are oppositely beveled, as at 80, to form a feathededge at the forward end of the plate.

The holding bar 60 extends through the openaoecyeo iiuictions g :2 downso fingers.

. elongated in the 2.0 is of length to project y 2. substantial distancebeyond the front of the trough The width of platform. is such as to haveits sides arranged over the sides of trough i2. The platform isprovided. with spa ed legs for seating upon the top edge of the frontWall 23 of trough G2. The platform C2; detechably secured upon the partsby set screws Arranged at the front of the trough i2 and leading tomotor is a controlling means B l for the latter.

The outer faces of the sides l5, it of trough l2 are formed with lugscoasting with the latching members 63 for detachably securing thesection 6 relative to section 5 in the position shown in Figures 1 and3. The controlling springs for members 63 are designated 86. The pivots5d are secured in the parts 68 of supports 29, 38 rearwardly of and inproximity to rod 58. The latching members 63 extend above said parts 68to be in convenient reach of the attendant.

The material which is to be acted upon is $21- dicated at 3'1. Thematerial is extended between guide rolls 56, 55, picked up and glueapplied to one face of the material by roll G6. The roll 56 causes thematerial to pass towards the pick-up fingers 57 and these latterfunction to direct the coated material in the manner as shown in Figure3.

When it is desired to clean roller 46, as well as rollers 56, 55, and 56and the fingers 5'5, the section 6 is released and swung to the fullline position shown in Figure 2. Section 6 is maintained in suchposition by the rod or bar 59 seating upon the holders 3i, By thisarrangement convenient access may be had to those elements of themachine which are to be cleaned.
